Bucket Elevator & Conveyor Hazard Monitor

WDC4V46CAI, WDC4V4CAI

The Watchdog Super Elite (WDC4) is easy to install and simple to set-up. The system processes signals from sensors for belt misalignment, belt speed & slip, continuous bearing temperature, pulley misalignment and plug conditions for bucket elevators or belt conveyors. When an alarm is detected it will sound an alarm and provide shutdown control of the elevator/conveyor and feeding system.

A 3.5” LCD screen displays the entire system status at a glance. Password protected controller settings can be set up either directly on the LCD screen, or by a PC application and transferred to the WDC4 via an SD card.
The Watchdog Super Elite can be connected directly to a PLC using the Modbus TCP/IP protocol, or integrated into HazardMon.com®. This secure cloud based solution provides live system status, graphs and historical data that is viewable on any web-enabled device (smart phone, tablet, desktop PC).

HazardMon.com® is a secure cloud based hazard monitoring solution providing status notifications and data logging for bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system's health is detected. An automated maintenance feature allows site operators to verify that all sensors on the system are operational and working correctly.

The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. This relay contact is used to immediately alarm and shutdown the machine.

Non-contacting extended range magnetic proximity sensor, not affected by dust or material build up, used to detect moving ferrous material up to 100mm away from the sensor. The WDA sensor can be used on bucket elevators to measure speed and alignment by sensing either the metal elevator buckets, or the ferrous bolts attached to plastic buckets. A more specialized use for the WDA switch is as a broken/slack chain detector on drag chain conveyors, or as a non-contact speed switch for screw conveyors.

The ADB series have been designed to allow the depth of the sensor to be adjustable depending on your application. A number of versions are available with probe lengths of 50, 100, 200 and 300 mm. The sensors screw directly into a bearing housing through a 1/4” BSPT threaded grease zerk. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor. The ADB series have NTC or PT100 type thermistors which allow for continuous temperature monitoring.

The WDB7 series is a lug style NTC thermistor or platinum RTD (PT100) type for continuous temperature monitoring. It is designed to bolt directly onto a bearing housing, motor, gearbox, or machine casing. The mounting hole is M8 which can be drilled out up to M10 diameter. The sensor can be connected to a PLC or to a hazard monitoring system, such as 4B’s T500 Hotbus Elite, Watchdog Super Elite, or T400 Elite. The connections are not polarity sensitive therefore special connections requirements are eliminated.

The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.

The Auto-Set series RF capacitance point level monitors are used for detecting high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers.

Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.

4B provides an extensive range of their own ATEX / IECEx / CSA /GOST- R approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.
